REVERSIBLE WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 542,488, dated July 9,1895.

` Application tiled March 19, 1895.

To all whom it may concern:

Be it known that I, CLEMENT SHARP MossoP, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in ReversibleWindow- Sashes, whichimprovement is fully set forth in the followingspecification and accompanying drawings. l

My invention consists of a novel construetion of a reversiblewindow-sash,by means of which said sash can be readily tilted orreversed as may be desired or required, pro- Vision being made forallowing the same to be swung on a suitable axis and to be locked whenin either of its eXtreme positions.

It further consists of novel details of construction, all as will behereinafter set forth.

Figure l represents a front elevation, partly in section, of areversible window-sash embodying my invention. Fig. 2 represents aVvertical sectional view ot the same. Fig. 3 represents a detail viewonan enlarged scale to be hereinafter referred to.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, `A designates a window-casing, and B and Cdesignate the upper and lower sash, respectively, thereof, and, sinceboth are `substantially the same, a description of 4one will suffice forboth. The said sash O has on each side thereof, adjacent to it, theupright strips D, to each of which a cord E is attached, said cordpassing over a suitable pulley F, journaled in the upper portion of thewindow-casing. strips D have inserted therein the thimbles G, which inthe present instance are threaded internally and have their ends tlushwith the edges of said strips D, said thimbles being held imlnovably inplace by any 'suitable means.

H designates plates which are suitably set into the faces of thewindow-sashes adjacent said strips D, and have, in the present in.-stance, an opening therein, through which passes the threaded portion Jof the stud K, the latter having a shoulder L thereon which acts as astop and is of substantially the same diameter as the thimble L', whichis adjacent to said plate H, said shoulder L being adapted to abutagainst a suitable bushing M, which Each of the said Serial No. 542,318.(No modal.)

suitable joints, as shown dottedin Fig. 3, may

be applied thereto for tu rning the same. Itwill be noticed, however,that the internal bushing M of the central stud is held against theshoulder of the latter by the plate N, so that the threaded portion J ofsaid centrally-located stud will always be in engagement with itsthimble G, said central stud on each side of the sash thus acting as anaxis on which the sash may be turned or reversed. l.

The operation is as follows: When it is Idesired to reverse thewindow-sash,the two outer stems on each side are screwed into theposition seen in Fig. l, out of engagement with the bushings G, thecentral stem remaining in the position seen, whereupon the'windowsashcan be readily turned or reversed, as seen dotted in Fig. 2. When it isdesired to raise the window, the same is turned into the position seenin Fig. l, and the outer studs are caused to engage their adjacentbushings, whereupon it will be seen that the sash C and the strips D oneither side can be raisedtor lowered in unison, as is evident.

` It will be apparent that, although I have shown three studs andthimbles, dre., in each side of each sash, the number of the saine maybe varied, if desired-e. g., in large windows tive studs with theiradjuncts may be employed, the central stud serving as an axis, while thetwo outer ones will serve to lock the window-sash in position relativeto the adjacent strips, which will have the cords E or their equivalentsattached thereto, as in the present instance. lt will also be apparentthat other changes maybe made by those skilled in the art, which willcome within the scope of my invention, and I do not, therefore, desireto be limited to the exact constructions I have herein shown anddescribed.

When it is desired to take the sash out, the

plates N are removed and the bushing M is withdrawn sufficiently toallow the inner end of the stud K to be moved out of engagement with theadjacent thimble G, the outer studs IOO K on each side being now 4in theposition seen, and the sash can be readily removed, as is evident.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

l. A window sash, strips on the sides thereof, having thimbles securedtherein, plates secured to the sides of said sash, having openingstherein adapted to register With said thimbles, studsmovable in saidsash and thimbles, and having shoulders adapted to abut against saidplates, and suitable stops for holding said studs in position, saidparts heing combined substantially as described.

2. A Window sash, a movable strip adjacent thereto, threaded thirnblesSecured therein, plates attached to said sash, and having thimblesextending therefrom, threaded studs provided with a shoulder mounted insaid last mentioned thiinbles, and bushings secured within the latter,and acting as a stop, substantially as described.

3. In a device of the character described, a

window sashand a strip D adjacent thereto, the threaded thirnble Gsecured in said strip, the apertured plate H and thimble L attachedthereto, the stud K mounted in said thirnble L', and having the shoulderL and squared portion P thereon, and the internal bushing M serving as astop, said parts being combined substantially as described.

4. In a device of the character' described, a Window sash, and a strip Dadjacent thereto, the threaded thimble G secured in said strip, theapertured plate H and thinlble L attached thereto, the stud K mounted insaid thimble L', and having the shoulder L, and squared portion I?thereon, the internal bushing M serving to hold said shoulder in contactwith said plate H, and the plate N for holding said bushing inposition,said parts being combined substantially as described.
